It consists of a 1\/4-inch liquid line and a 3\/8-inch suction line, each wrapped in 1\/2-inch insulation, running a total length of 50 feet. The insulation jacket reduces heat gain on the suction line and protects both lines from abrasion and UV exposure in exposed-run installations. This line set ships coiled and is handled by licensed HVAC technicians during mini-split commissioning.\u003c\/p\u003e\n\u003cp\u003eThis line set is suited for residential and light-commercial ductless split system installations where the indoor and outdoor units are separated by up to 50 feet of refrigerant piping run. It is commonly used in single-zone and multi-zone applications where the 1\/4-inch and 3\/8-inch line combination matches the equipment manufacturer's specified connection sizes. The 50-foot length provides flexibility for installations where the condenser is mounted at grade or on a rooftop with a long wall penetration run.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/4-inch liquid line and 3\/8-inch suction line pre-paired for ductless mini-split use\u003c\/li\u003e\n  \u003cli\u003e1\/2-inch insulation wall on both lines reduces heat transfer and protects against abrasion\u003c\/li\u003e\n  \u003cli\u003e50-foot run length accommodates longer-distance indoor-to-outdoor unit separations\u003c\/li\u003e\n  \u003cli\u003eShips coiled for easier routing through walls, ceilings, and line-set covers\u003c\/li\u003e\n  \u003cli\u003eWeighs 10.72 pounds for manageable single-technician handling on most installs\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation line set for ductless mini-split systems requiring a 1\/4-inch liquid line and 3\/8-inch suction line configuration.

Power down and lock out the indoor and outdoor units before connecting or disconnecting refrigerant lines. Evacuate the line set to manufacturer-specified micron levels before releasing refrigerant charge. Avoid kinking the copper tubing during uncoiling and routing; use a tube bender for directional changes to maintain proper flow cross-section.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLiquid Line Diameter\u003c\/strong\u003e: 1\/4 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSuction Line Diameter\u003c\/strong\u003e: 3\/8 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsulation Thickness\u003c\/strong\u003e: 1\/2 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLine Set Length\u003c\/strong\u003e: 50 feet\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 10.72 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoiled Package Length\u003c\/strong\u003e: 32.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoiled Package Width\u003c\/strong\u003e: 32.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoiled Package Height\u003c\/strong\u003e: 6.5 inches\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: MUELLER STREAMLINE\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: LS-1\/4X3\/8X1\/2X50\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MUELLER STREAMLINE","offers":[{"title":"Default Title","offer_id":51268844618034,"sku":"LS-1\/4X3\/8X1\/2X50","price":328.45,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/308913427.webp?v=1780707330","url":"https:\/\/voomisupply.com\/products\/mueller-streamline-ls-1-4x3-8x1-2x50-line-set-50-ft","provider":"Voomi Supply","version":"1.0","type":"link"}
